CAR-DOOR-LOCKING DEVICE.

To all 707mm it m (152 concern Be it known that l, Finn) Bnnewnnn, acitizen of the United States residing'st Chicago, in the county of'Cookand State of Illinois, have invented a certain new and usefulln'lproven'lent in Cer-Door-liocliing Devices of which the following isa speciliczition.

This invention relates to car-door locking devices and. has for itsobject to provide a new and improved device of this description. @110 ofthe ditiioult "problems in nonnection with trsnspoii'ti materials by'rzril \vziy cars is to prevent the cur doors from being surreptitiouslyopened, and the ()liject ot the present invention is to provide at cardoor locking device which will hold the door in its closed position andprevent access to the cur by springing the edge 01? the door and. whichwill also indicate any tnni'perin4 with the lock. The invention isparticularly znlzrpted to be used in connection "with Ill'fll'lgibleseals. The invention is illustrated in the accompanying drawing,wherein- Fig. l is a, view with parts broken away showing s car doorwith the loclchig device applied. v v

having an opening 9 for the locking pert 5. i lhe plate'S is arrangedwith a beveled time 10 and the projection T is provided with e beveledface 11. It will thus be seen that-when the looking wzirdly throughthe'plate 8 and is then rotated, the beveled faces on the plate 8 andthe projection 7 are brought into engagexnent and the door 1 is clampedagainst the, side of the car. The front of the door, when closed, abutsagainst a stop 1?. The opening 9 in the plate 8 is not a circularopening but has one dimension greater then the other,

so that the projection 7, when the lodlzing part is turned in oneposition may easily 7 the car door has segged down. The locking part 5isarran 'ed so that it may be moved longitudinally Well as rotated, sotlnit after the projection [7 has been (lisei'lgaged troni the platepert, may then be moved longitudinally through the opening 9 in theplate so as to become entirely disengaged from the cor body. I alsopreter to arrange the conthe locking part 5 moved longitudinally to itsunlocked position it can not be rotated so that the part 7 will alwaysbe in proper position to enter the opening 9. I further prefer toarrsn'ge the parts so that after the locking part is moved to itslocking position and rotated to cause the projection 7 to engage plate8, it can not then be moved longitudinally but can be rotated. l securethis result by providing a stop 12 which engages a shoulder l3 when. thelocking part is inits locked position,- so as to prevent longitudinalmovement; thereof, When the looking part is in its unlockedposition,rotetion thereof is prevented due to the ear 'thst e false 1%eng rges the stop 12, said tsce'sliding under the stop '12 when thelockingpert is lnoved to its unloolred position In the sonstructionshown, the stop 12 eonsists is a in extending between the branches or epart is moved in- 6 though 8 by rotating the locking 8 ided Tait "the 1,

front of the base -:l with a projection 16 which projects out over thebase. This projection is recessed at 17 to provide portion of thereceiving space for the frangible seal 17 shown in dotted lines and isalso provided with a seal breaking part 18, which engages theoverhanging parts 19 and 2b, which prevent lateral movement thereof.After the seal is placed in position, it is held from removal by therotating part 20, which has an over-lapping end 21 which overlaps theseal. This rotating part 20 may be rotated in one direction, but can notbe rotated in a reverse direction, and it is provided with an engagingface 22 which engages the frangible seal when the part 20 is in itsoperative position, and prevents any further rotation in the forwarddirectioi'i without breaking the seal. The rotation in the reversedirect on is prevented by means of a pawl 23 which engages teeth 24 onthe stemof the part 20. The pawl is elastically held against the toothportion by means of a springv 25. The stem of the part 20 passes throughthe base 4- and the tooth portion and pawl are concealed back of thebase so as not to be accessible. The base l is fastened to the car doorso that it can not be removed from the outside, as for example, by bolts1 which pass through the door and which are provided with nuts ,1 on theinside of the door, so that when the door is closed, the base 4 can notbe removed. Some means is preferably provided for stopping the handle 6when the locking part has been moved to its unlocked position and beforeit is moved laterally to bring the flat face of thelocking part underthe pin 12. In the construction shown, this result is produced. by meansof a suitable stop, as for example, by the face of the part 16 strikinga stop face 26. This is shown by the dotted lines in Fig. 1. Means arealso arranged for stopping the handle when the locking part has beenrotatedto its locking position. This may be accomplished by means of aprojection 27 which engages a stop 28 (see Fig.1). I may arrange thedevice so that a wire, tin or other looped seal may be used. This may beaccomplished by providing slots 27 and 27 in-the parts 37 and 28, sothat when they are in the position shown in full lines in Fig. 1 thissea]. may be looped through them. I have described in detail aparticular construction embodying the invention but it is, of course,evident that the parts may be varied in many particulars withoutdeparting from the invention, and I do not, therefore, limit myself tothe particular construction shown.

The use and operation of my invention are as follows When it is desiredto lock the door. the door is slid to its closed position and by meansof the handle 6 the locking part 5 base, a locking is movedlongitudinally until the projection '7 passes through the opening 9. Thehandle is then rotated until the projection 7 engages the plate 8 asshown in Fig. '1 he stops then prevent further rotation of the handlewhich is in the position shown in full lines in Fig. 2. The rear of thedoor is now locked and tightly pressed and clamped against the car bodyand is hold both against sliding and agaii'ist being pried out or movedaway from the car body, thus completely preventing access to the car.The front of the door abuts against the Part 1 and hence can not betampered with. The frangible seal is now placed in position and therotating part 20 rotated until the projecting part 21 projects over theseal. The handle (5 can not now be moved without breaking the seal. llhen it is desired. to enter the car, the the seal-breaking part 18engages the edge of the frangible seal and breaks it, thus permittingthe locking part to be rotated. The locking part 5 is then movediongitudinally as shown in Fig. 5 the projection '7 being thus movedthrough the opening 9 disconnecting the loci; from the car body. Thedoor can then be slid to one side. It will thus be seen that by means ofthis construc tion the door is held so as to completely excludeunauthorized persons from the car and that any unauthorized person canonly getinto the car by breaking the frangible seal. and thus disclosingthat the car has been tampered with.
